Abstract EN
Wireless Sensor Networks (WSNs) are a growing research area as a large of number portable devices are being developed.
This fact makes operating systems (OS) useful to homogenize the development of these devices, to reduce design times, and to provide tools for developing complex applications.
This work presents an operating system scheduler for resource-constraint wireless devices, which adapts the tasks scheduling in changing environments.
The proposed adaptive scheduler allows dynamically delaying the execution of low priority tasks while maintaining real-time capabilities on high priority ones.
Therefore, the scheduler is useful in nodes with rechargeable batteries, as it reduces its energy consumption when battery level is low, by delaying the least critical tasks.
The adaptive scheduler has been implemented and tested in real nodes, and the results show that the nodes lifetime could be increased up to 70% in some scenarios at the expense of increasing latency of low priority tasks.
